Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTET040252 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 4 positions at 0.300" (7.62mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Connector Type: Female socket plugs with screw termination are required to maintain functional equivalence.
• Mounting Configuration: Free-hanging in-line mounting must be preserved.
• Electrical Ratings: Substitute parts must meet or exceed the 300 V UL voltage rating and support 8-24 AWG wire gauges.
• Compliance Standards: RoHS3 compliance and UL94 V-0 flammability rating are mandatory for regulatory equivalence.
• Torque Specification: Screw torque of 0.79 Nm (7.0 Lb-In) ensures consistent termination across equivalent parts.

The ET0402520000G from Amphenol Anytek satisfies all critical substitution parameters while offering enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ET0402520000G is a direct functional substitute for the OSTET040252. Both components maintain identical mechanical interfaces, pitch specifications, and screw termination torque values. The substitute part exceeds the original voltage rating (600 V vs. 300 V) and extends the operating temperature range (-40°C to 115°C vs. -33°C to 105°C), providing enhanced performance margins for demanding applications.

Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory equivalence. The ET0402520000G holds active product status with confirmed inventory availability, eliminating obsolescence concerns associated with the original OSTET040252.

Frequently Asked Questions (FAQ)

Q: Can ET0402520000G replace OSTET040252 in existing designs? A: Yes. Both components share identical pitch (0.300"), position count (4), termination style (screw), and mounting configuration (free-hanging in-line). Screw torque specifications are identical at 0.79 Nm (7.0 Lb-In).

Q: What are the key differences between these parts? A: The ET0402520000G provides higher voltage rating (600 V vs. 300 V), extended operating temperature range (-40°C to 115°C vs. -33°C to 105°C), and active product status. Wire gauge compatibility remains 8-24 AWG for both parts.

Q: Are there compliance or certification differences? A: No. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. Regulatory equivalence is maintained.

Q: Does packaging affect substitution? A: The ET0402520000G is supplied in bulk packaging. Verify packaging requirements for your procurement process, but this does not affect functional or electrical compatibility.

Q: What wire strip length should be used with the substitute part? A: The ET0402520000G requires 10-11mm wire strip length, compared to 7-8mm for the original OSTET040252. Adjust wire preparation procedures accordingly during installation.
